Connected to Wifi but No Internet - HELP!

[HardHitter2k14]

Some of my devices are not working with wireless. They show connected to the router but then "No Internet Access" message with the yellow triangle ! is showing up.

It is only for some devices (which worked perfectly before) while the other devices on the network work fine.

See summary below:

Work Laptop: "No Internet Access"
Personal Laptop 1: "No Internet Access"
Personal Laptop 2: Internet
Phone: Internet

What is it that I should be checking to get the other devices working? It is obviously something with the devices and not cable service/modem/router

What band (N, G, 2.5ghz or 5ghz)? What security are you using on the router? WPA? WPA2? Maybe the problem systems can't connect to that band, or they aren't able to use the security configuration. I'd guess security.

I guess I have to pre-req this in saying that I moved my router/cable modem from the living room into the laundry room because there is a huge switch there that feeds the jacks throughout the house (so I can hardwire devices).

This problem occured when I moved it to the laundry room. I just moved it back to the old setup and everything works as it was before.

I'm wondering if using a cable with a weak signal would cause these problems? I don't think it's the cable because once again, some devices connected/ran and some connected but would have "no internet" Also to clarify, these were all devices that were already on the network prior to the move.

Network needs to be connected in a certain way, One can not just move devices around because the plug/jack can be physically plugged.

The WAN port of the Router needs to be connected to a Modem, what it is connected to right now?

Or, it might be that your is signal is low and unbeknown to you the devices that connects actually connects to someone else open WIFI.

Yep I understand that. So I have a box in my laundry room that has out the outside cables going into it. It is basically like a central hub for the entire house. All of the ethernet jacks throughout the house, has the wires going from the jack in whatever room it may be in, running wires throughout the wall/house and then into this big box which I believe is just a huge switch called Packetfront.

So initially, when the cable modem and router were up in the living room, I had a wire coming from the wall, into the cable modem to get the feed, then a ethernet cable from the CM into the router.

Now when I moved it downstairs, I tried to find the source for the internet. I found a cable and plugged it into the CM and saw my CM got all lights lit up. I then connected the ethernet cord into the router as I did upstairs and then took a ethernet cord from one of the router spots and fed that into the Packetfront. Once I did that, the router now had something like 40 connections wired to it.

I can't figure out why some of the devices worked on Wifi and some didn't when I had it setup that way.

Check your DHCP reservation pool. If it is set for less than 40 devices, then some devices wouldn't get IP addresses, and wouldn't get internet.

I'm assuming that is going to be in the router settings?

Figure out which wire is going from the box to the room where the cable modem is/works. Unplug it and plug a jumper from the modem to THAT port in the box. It should work fine. Keep the wireless router outside and away from the box. The metal cabinet and wires may be causing issues. Test the connections IN the basement ans rule out that it's not issues where your moving the router out of range.

Don't quite I follow you right now.

The reason why I want to move the modem and router down to where the box is is because I don't want to have to run a wire down the wall to get to the box.

Is that what you are referring in doing?

 

[QuietDad]

Figure out the wire/port in the box that runs to where the modem works. When you move the modem to the box, plug the router there. If it's a router modem combo, place it outside the box. If they are separate, the modem can go in the box, but keep the router outside of it. Your trying to run the wires EXACTLY like the are when it works. Wireless antennas can become worthless inside the box, especially if it's metal.
Another issue is moving the router downstairs, the devices trying to hook to it are now out of range. Set it up, try and connect each device in the room with the modem to verify the connection, then try where you want them to work

Bringing this back up as I am working on it today

So to recap, I've brought the cable modem and router from the living room to the laundry room. Within the laundry room is the "central hub" of the house where all of the wall sockets and cables run into.

I have the Comcast cable from the outside connect directly into the cable modem. From the cable modem, I have a ethernet cable going from the cable modem into the router. With this current setup everything works flawlessly.

In order for me to get wired internet throughout the house, I have to feed the "packetfront" as all of the lines go into that. From the router, I have another ethernet connection going into the Packetfront. Once this happens, this is where problems start happening. Everything works flawlessly for 5-10 minutes (wireless on my phone, wireless on my laptop, and hard line into another laptop) and then it changes to "limited" connection.

With that said I'd assume the problem is the packetfront, but if that was the case, I would think that the hardline only would be Limited and wireless would be fine.

Thoughts?

Here is the "Central Hub"

This shows the direct line into the cable modem

Shows the cable modem feeding the router

Shows the ethernet cable being fed into the PacketFront

Does this also happen if you connect only one device? Wireless or ethernet doesn't matter, the point is one single client on your network. Change the Wi-Fi name (SSID) and passphrase to something you haven't used before (or disable Wi-Fi completely), to ensure that no other device lying around connects and messes with the troubleshooting.

Sounds to me either like a small DHCP pool as already suggested by VirtualLarry (you increase the size of it in the router settings), a loop somewhere, or some other network device announcing itself as a gateway. Do you have Windows Internet Connection Sharing running on any devices?

Start at the beginning. Everything worked until you switched to a different coax connection. Are you certain that connection comes right from the drop to the house and that there are no splitters upstream of it? I see a lot of coax wires and a splitter and at least three cables not connected. This is where I would be starting especially if I was not present when all this hardware and wiring was installed or if I had not done it myself.

You've got one coax cable feeding that splitter. Where does that come from or run to? One in, many out usually means the single cable is the source. Does that come in directly from outside? Without being physically present to start manipulating the wires it's hard to tell from the pictures.

This is my next area of questions but I don't want you to get distracted by it because the basics as outlined above needs to be dealt with first.

Your pic of the Router appears to show one CAT cable attached. It's a little tough to tell if it's plugged in or running underneath though. Assuming that it's running from the Modem to the Router and plugged into the WAN port, is the blue CAT cable running from the PacketFront that runs down and disappears plugged into a LAN port on the Router? We can't see the whole Router. Just making sure the basics are covered. You seem knowledgeable enough to know all this, and some things are working, I'm just making sure.
